Mad Men star Jon Hamm has said that it was a "great honour" to voice a character in an upcoming episode of The Simpsons.

It was previously announced that Hamm would play an FBI agent in the long-running Fox animation.

"It was an incredible experience," he said. "I got to work on The Simpsons, which I watched for 20 years and the show is still fresh and still funny and the characters still resonate. It’s one of the best shows on television. It was an honour to be asked to be a part of it.”

Hamm joked that dressing for the voice recording was a lot easier than for Mad Men, in which he plays the dapper Don Draper.

“I don’t have to get dressed [for The Simpsons]!” he quipped.

The episode starring Hamm is expected to air in December. The fourth season of Mad Men will premiere July 25 on AMC.
